General principles, applied to life insurance and annuities
Warning: This is a piece for techies, not for ordinary folks!
Recently I’ve come across a number of pieces, or listened to podcasts, about insurance. It occurred to me that the basic principles involving the need for insurance are relatively simple, though they’re often obscured by a mind-numbing amount of detail that includes aspects of personal taxation in the country of origin of the article or podcast.
I’ve set this out before, in different contexts, so you may recall seeing something like this before. As I looked at what I’ve written, it seems to me that the principles are (a) simple, (b) not sensitive to the time of writing, and (c) applicable anywhere. So I’m reproducing the principles in this blog post, and expanding their application to a topic that seems to have gained relevance recently, which is the need (or not) for income streams guaranteed to last for life.

Let’s start with life insurance. Why would you need it? In fact, why would you need any form of insurance at all? (Your home, your car, your life, whatever.) It’s because the future is uncertain, and there are some outcomes that can leave us (or our survivors) financially badly off; and even if we can’t completely avoid those uncertainties, we’d like to do something about the negative financial impact if one of those bad events occurs.
There’s a quick common sense sort of way to think about such events, shown in the table below. This considers future risks in two ways. One way is: how likely is the risk to happen? Is there a high probability that it will occur, or is the probability low? The other way is: how big a financial impact will it have, if it occurs? A high or a low impact?
Risks and financial impacts
High probability | Low probability | |
High impact | Budget for the expense | Pool risk; buy insurance |
Low impact | Budget for the expense | Accept minor disruption |
Here’s what the table says. If there’s a good chance (a high probability) that the event will happen, build the impact into your budget, whether the impact is big or small. Don’t let the event surprise you. After all, it is likely to happen. In the unlikely event that it doesn’t happen, that’ll be a pleasant financial surprise for you.
How about an event that’s unlikely to happen (low probability), but if it does, the impact will be small? Typically, that’s not worth bothering about. Even if it does happen, it won’t disrupt your financial situation much, because its impact is small. You may even have a small reserve for these unexpected events – I hope you have your Life Happens fund (or fund for emergencies, as it’s more prosaically called).
Now look at the box that represents something unlikely to happen (low probability), but if it does, it’ll have a big impact. That’s the situation you want to avoid, and that’s when insurance is generally indicated. Think of insurance as a form of pooling your risk with the same risk that others face.
For example, fire insurance for our homes. According to statistics available on the internet, the chance that a person’s home will catch fire in any given year is far less than 1%. But if there is a fire, it can do enormous damage. We don’t keep a personal reserve fund large enough to replace the home – that would be the equivalent of owning two homes! So we pool our risk exposure with others by buying a fire insurance policy. The premium (apart from the insurance company’s loadings) is essentially the product of the probability of occurrence and the likely financial impact. And commonly, the product is a small number. So the premium tends to be small and acceptable, and if we don’t have a claim, that’s just fine. We don’t mind losing the premium.
Now apply that principle to your life. The chance of passing away in any given year is small, while we’re working: it doesn’t even reach 1% until we’re close to retirement. But if we have dependents, the loss of working income if we do pass away can be devastating. So a logical step would be to consider buying term insurance that replaces the lost income, the term ending when work is projected to end. And since the lost income declines by one year’s worth every year, a logical consideration might be what’s called a “decreasing term insurance,” where the amount paid on passing away is very large if that event happens when we’re young (because our dependents lose many years of our income) and the amount declines to zero at the projected retirement age. (Yes, you can and probably should complicate matters by projecting inflation, but that doesn’t change the principle.)
Of course there are many other considerations involving life insurance, which potentially has uses beyond the replacement of working income. But I’ll leave those for the experts to explain, particularly since some considerations depend on laws and taxation, both of which vary from one country to another.

Now let’s look at these principles in a different context, the context of unexpectedly long life. Emotionally that’s something we all hope we’ll encounter, particularly if we can stay healthy; but from a purely financial perspective (which is the only perspective I’m considering) it’s a risk. Should you buy insurance against it? Well, let’s look at the principles.
The starting point is obvious, yet (in a way) not at all obvious, because it’s invariably ignored. And it’s that insurance only makes sense when there’s a low chance of a financially negative event happening. Apply that to longevity. It means there’s no point considering longevity protection until the chance of outliving the age selected is low.
What does “low” mean? Anything you like, of course; it’s surely a personal decision. But surely it must mean a lot lower than 50%. In discussing fire insurance for a home, we were talking of a less than 1% chance. The same 1% chance applied to longevity would mean insuring against the chance of living beyond age 100 (or thereabouts – it obviously depends on the table used). (Also, I’m talking about the expected survival years starting from birth. If you start from let’s say, age 65, meaning it’s already a long-lived group we’re considering, the survival age would be even higher than 100.)
Gosh, in turn that implies budgeting for living up to that age – very, very expensive! Yes, but that’s what makes the cost of insurance bearable, because it’s only the last 1% of the survival table that we’re insuring against.
OK, then, let’s consider insuring against the last 10% of the survival table. That would be more expensive, obviously, because we’re hedging an event with a 10% probability. What age would that imply? Roughly age 95. So let’s get this straight: the cost of that insurance is becoming noticeable (never mind the actual calculations and amounts: the concept of insuring against a 10% probability intuitively begins to feel high) and we still need to budget for living to age 95.
OK, then, let’s go to a 25% chance of survival. Obviously this would feel very expensive. But what age would it take us to? Answer: roughly age 90. And it would require budgeting for survival to age 90. Both parts (budgeting and longevity protection) would seem very expensive.
Yet consider what longevity protection is actually available. Insurance policies providing protection against the financial condition of living a long time are called “deferred annuities,” and (in countries where they’re available at all) typically the highest age for commencing the insurance payments is 85. (They have a reason for that, but let’s ignore the reason; it doesn’t change the argument.) Typically there’s more than a 40% chance of surviving to that age from birth. If you’ve already survived to age 65, typically there’s a better than 50-50 chance of surviving to age 85. And that’s for a single person. For a couple, the chance is much higher than 50%: typically the chance that at least one member of a 65-year-old couple survives to age 85 is higher than 75%.
Well, you don’t buy insurance against an event that is either 50% likely (for a single person) or 75% likely (for a couple). That’s ridiculous. The cost would be horrendous. And it is. Remember what I said about sensible insurance, near the start: we don’t mind losing the insurance premium if the event doesn’t occur, because the premium is small.
Well, that’s not the case for longevity insurance with payments commencing at age 85. And that’s why people are reluctant to buy such insurance. Losing the premium by not surviving to age 85 would mean losing a lot of money. And so typically the few people who do buy such insurance specify that, if they pass away before 85, the premium is refunded to the estate. Well, my goodness, what that means is that the true premium (the amount that would be lost if the event, the survival, doesn’t occur) is only the interest that the premium would have earned – which is a small proportion of the premium, and therefore buys relatively little actual insurance – and in turn that makes the insurance seem even more expensive.
To sum up: longevity insurance offering to start payments from age 85 is (typically) better budgeted for rather than bought. Not until (let’s say) age 95 does it really make sense to buy such insurance. And that’s not offered anywhere.
How about an immediate annuity?
Same thing. The odds are strong that you’ll be alive next year. Why insure against survival? Budget for survival. It’s death that you might want insurance against, not survival.
No wonder annuity purchases are relatively few. There’s not really an “annuity puzzle,” which is the technical name for the (apparent) mystery as to why so few people buy immediate annuities. They only make sense if your sole goal is to maximize the guaranteed lifetime income you want, and don’t have a problem losing the purchase price if you are unfortunate enough to die early (as Menahem Yaari established mathematically in 1965.) No wonder even the relatively few annuities that are purchased need to specify something like a return of the remaining premium if the purchaser dies early (thus noticeably reducing the amount of the annual income payable, relative to a policy without that return feature).
Well, this has turned out to be a diatribe. I didn’t intend it, but I don’t withdraw it.

Takeaway
Insurance may be valuable when the chance of an event is low but also its financial impact is high if it occurs. Longevity insurance, as offered these days, doesn’t fit these criteria, because the event being insured against has a relatively high likelihood of occurring.

I have written about retirement planning before and some of that material also relates to topics or issues that are being discussed here. Where relevant I draw on material from three sources: The Retirement Plan Solution (co-authored with Bob Collie and Matt Smith, published by John Wiley & Sons, Inc., 2009), my foreword to Someday Rich (by Timothy Noonan and Matt Smith, also published by Wiley, 2012), and my occasional column The Art of Investment in the FT Money supplement of The Financial Times, published in the UK. I am grateful to the other authors and to The Financial Times for permission to use the material here.
Hello Don,
Life annuities have long been the perfect decumulation solution as they have longevity insurance embedded in them, but have been bedeviled by high fees, the risk of insurer insolvency, and selection bias. To paraphrase the old saying about Brazil – annuities are the solution of the future, and always will be. On the bright side, Brazil has put into effect a remarkable annuity program known as Renda+. Any citizen can go to the Renda+ website (https://www.tesourodireto.com.br/rendamais/), answer 4 simple questions, and contribute to an inflation-adjusted forward starting annuity (starts at age 65). The contributions can be as small as Reai 30, and will be automatically deducted from the purchaser’s bank account. At age 65, inflation-adjusted payments are automatically deposited to the purchaser’s bank account (or to that of a beneficiary if the purchaser dies prior to the start of the annuity). Hopefully, this Brazilian tail will wag the global dog!
Tom
Thanks, Tom. You’ve prodded me into studying the Merton/Muralidhar papers on which the Brazilian program is based, and I’m so impressed that I plan to write a blog post about it. So, double gratitude to you!
Don, very lucid and thoughtful. Thank you. I am going to forward it to my financial advisor.
The rule of 85 you refer to seems very strange. I understand why from one perspective it is necessary to return the premiums. But it defeats the idea of insurance. (Is the expression “tontine”?)
Thank you. Richard
Thanks. It’ll be interesting to see what your advisor thinks. Re the word “tontine”: these days it seems to be applied to all sorts of situations, though with the common element of longevity risk pooling.
Hi Don
I love the simplicity of whether or not to insure. The ‘more simple’ we can make it for the average person, the easier it is for them to understand and to take it up.
I think you have repeated a concept that misses part of the value of the annuity. The annuity is a combination of an investment vehicle and an insurance product.
Retail investors cannot access a pure longevity insurance product.
Your concept of an investment up to age X and insurance beyond can be provided by an annuity. The annuities sold in Australia (in increasing numbers) actually do that up to age 85 by providing the death benefit. This provides an unused value back to the annuity owner.
The key difference is the conversion of capital to income. In order to budget for living longer, a retiree needs to spend less. The reduction in spending is the self-insurance cost and results in capital that the retiree will leave to the next generation if they don’t reach the target age.
Some back of the envelope numbers might help here. (based on indicative prices).
Each strategy is to invest up to age X and purchase a deferred lifetime annuity (DLA) for all spending after age X.
1. No deferral- Annual spending available: $72,000
2. DLA from age 75- Annual spending $66,000
3. DLA from age 85- Annual spending $61,000
4. DLA from age 95- Annual spending $55,000
The insurance cost is lower in the later deferral, but the need to budget for an extra 10 years reduces the level of spending available.
The lost income will be left as the surprise bequest. In example 4, if someone dies at 85, rather than 95 their estate would get the residual $450,000 in the investment account. (or $760,000 at age 75). Case 3 would only leave $500,000 if death was at age 75.
I wouldn’t recommend any of these exact approaches, but this contrived example highlights the trade-off.
The cost of insurance increases with probability, but the cost of self-insurance can be even higher.
Everything you say is absolutely right, Aaron. (And thanks very much, too, for the spreadsheet you sent me separately – outstanding work, very clear to understand.) I think, though, there may be situations beyond the one you’ve outlined. Here’s what I mean.
Let’s start with the situation behind your calculations. Let’s suppose the individual has no bequest motive, or has removed assets that constitute the bequest and that therefore we’re considering only assets with no bequest motive attached. Then your analysis is spot on. An immediate annuity is easily superior to a deferred life annuity with self-insurance up to the time the deferred annuity kicks in: exactly as you say. This illustrates Yaari’s conclusion that, if the sole motive is to maximize a guaranteed level of income for life, an immediate annuity does it best. And (this is an explanation I hadn’t realized, until you mentioned it – brilliant!) the difference arises from the surprise bequest, which the immediate annuity doesn’t create.
If (as in your example) $72,000 a year meets all your goals, then there’s no need to do anything but buy the immediate annuity. Your purchase price (your accumulated assets base) is enough for everything you desire. As the saying goes, you’ve won the game, and if you’ve won the game, why take any further risk?
But if that $72,000 isn’t enough for all you’d like to do, then you might be inclined to take some further investment risk, and that’s when the benefit of a deferred life annuity reveals itself: to take care of the longevity uncertainty, which by age 75 exceeds the financial uncertainty of being 100% invested in equities. And that’s also when it makes sense to divide your financial goals between Needs and Wants, and consider locking in the Needs with an immediate annuity, so that any investment risk you take affects only the Wants. There’s much more to be said on this subject, but my purpose is simply to distinguish between “I’ve got enough” and “I still think I should take some investment risk to be able to achieve my desires.” I suspect many (most?) retirees may feel they don’t have enough for Wants as well as Needs.
